Geni is a new ‘Web 2.0′ start-up company with a mission to build a complete family tree for humanity.
One particularly neat aspect of the site is that you can immediately start entering your information from the moment you arrive at the site. No signing up, checking emails, logging in, etc. Just visit the url and start entering information.
It’s also viral. You add the email addresses of your family members and they can access your tree and start adding information. Eventually, the trees start to merge and a larger family tree is created.
Could this have implications for medicine? - could we help track hereditary diseases through this kind of system?
Geni have a nice overview of their service on their blog.
